Exhibit 10.2


 


FORM
OF Series
2 notes debt conversion AGREEMENT


 


This Debt
Conversion Agreement (this “Agreement”) is made as of July 2, 2018 (the “Effective
Date”), by and among NeuroOne Medical Technologies Corporation,
a Delaware corporation (the “Company”), and each holder identified on the signature page hereto (each,
a “Holder” and, together, the “Holders”).


 


Background


 


In August 2017, the
Company entered into a subscription agreement and issued interest free promissory notes to certain accredited investors. In November
2017, the Company and each Holder amended the notes. In March 2018, the Company and each Holder entered into a written consent
to amend and restate the promissory notes (as amended, the “Notes”) and to amend the subscription agreement
to replace the form of warrant agreement annexed to the subscription agreement (the “Replacement Warrant”)
and to provide for the issuance of an additional warrant (the “Additional Warrant” and, together with
the Replacement Warrant, the “Warrants”). In March 2018 the Company issued and delivered the Notes, the
Replacement Warrants and the Additional Warrants to the Holders. Unless otherwise provided, capitalized terms used in this Agreement
but not defined herein shall have the meanings given to such terms in the Notes.


 


The Notes, as amended
in March 2018, are now convertible promissory notes that bear interest at a fixed rate of 8% per annum and require the Company
to repay the principal and accrued and unpaid interest thereon on July 31, 2018 (the “Maturity Date”).
If the Company consummates an equity or equity-linked round of financing resulting in more than $3 million in gross proceeds (the
“Qualified Financing”) before the Maturity Date, the outstanding principal and accrued and unpaid interest
on the Notes shall automatically convert into the securities issued by the Company in the Qualified Financing based on the greater
number of such securities resulting from either (i) the outstanding principal and accrued interest on the Notes divided by $1.80
or (ii) the outstanding principal and accrued interest on the Notes multiplied by 1.25, divided by the price paid per security
in such financing. The Notes are also subject to conversion in the event of a Change in Control transaction (or the Company’s
IPO) (the date of any such conversion of the Notes in connection with a Change in Control transaction, IPO or Qualified Financing
is referred to herein as the “Conversion Date”).


 


If the Notes convert
in connection with a Qualified Financing, each Replacement Warrant grants the Holder the option to purchase up to the number of
shares of capital stock of the Company equal to the shares of capital stock received by the Holder upon the conversion of the Note
at a per share exercise price equal to the actual per share price of the securities issued in the Qualified Financing. Each Additional
Warrant grants the holder the option to purchase up to the number of shares of capital stock of the Company equal to the product
obtained by multiplying (i) the outstanding principal amount of the Note held by such holder and (ii) 0.75.


 


The Warrants are exercisable
commencing on the Conversion Date and expire on November 21, 2021.


 






     


     


    

 


The Company and the
Holders desire to: (a) convert the Notes into shares of the Company’s common stock, $0.001 par value (the “Common
Stock”) as set forth in this Agreement; (b) cancel and extinguish the Notes; (c) amend and restate the Warrants as
set forth herein and (d) provide for the issuance of new warrants as consideration for the early conversion of the Notes.


 


Now,
Therefore, in consideration of the foregoing and for other good and valuable consideration, the receipt and sufficiency
of which is hereby acknowledged, the Company and each Holder hereby agree as follows:


 


Agreement


 


1.
Acknowledgement and Agreement. The Company and the Holders acknowledge and hereby agree that this Agreement will (a)
convert the Notes held by the Holders into shares of Common Stock, (b) cancel and extinguish the Notes held by the Holders, (c)
irrevocably cancel and extinguish the Warrants held by the Holders in exchange for the amended and restated replacement warrants
in the form attached hereto as Exhibit A (the “Amended and Restated Replacement Warrants”) and
the amended and restated additional warrants in the form attached hereto as Exhibit B (the “Amended and Restated
Additional Warrants” and together with the Amended and Restated Replacement Warrants, the “Amended and
Restated Warrants”) and (d) provide for the issuance of new warrants (the “Payment Warrants”)
as consideration for the early conversion of the Notes. Only the Holders that execute this Agreement will be subject to the provisions
herein.


 


2.
Conversion of the Notes.


 


(a) Notwithstanding
the terms of the Notes, the Subscription Agreement and the Warrants and notwithstanding that conditions to the occurrence of the
Conversion Date have not yet occurred, the Company and each Holder hereby agree that as of the Effective Date, any and all principal
and accrued and unpaid interest due and owing by the Company to such Holder (the “Outstanding Balance”)
under that certain Note shall be converted into shares of Common Stock (the “Conversion Shares”) based
upon the Outstanding Balance divided by $1.80. If conversion of such Holder’s Note would create a fractional share or a right
to acquire a fractional share, the Company shall round to the nearest whole number.


 


(b) The Company
hereby agrees to issue to and in the name of each Holder and cause such issuance to be recorded on the books and records of the
Company the number of Conversion Shares set forth opposite the name of such Holder on Schedule I hereto in consideration
for the conversion and cancellation of such Holder’s Note.


 


(c) Upon issuance
of the Conversion Shares to each Holder, such Holder’s Note shall be deemed cancelled and extinguished, without need for
surrender to the Company of the Note or any other further action by any of the parties to this Agreement, and such Note shall thereupon
be null and void and have no further force or effect. Each such Holder agrees that, as of the Effective Date, except for the right
of such Holder to receive Amended and Restated Warrants and Payment Warrants pursuant to Section 3 of this Agreement, all rights
and obligations of such Holder with respect to the Note or of the Company with respect to the Note (including the obligations to
(a) pay or cause to be paid all amounts due under the Note or (b) issue conversion shares upon the conversion date, as set forth
in Section 5.1 of the Note), the Subscription Agreement and any related agreement of such Holder, including, without limitation,
any related document entered into with respect to such Note, shall terminate. The termination of the rights and obligations of
such Holder with respect to the Note as set forth in this section shall not affect the rights and obligations of such Holder as
provided in the Amended and Restated Warrants. Each such Holder agrees to execute such documents and other papers and take such
further actions as may be reasonably required or desired to evidence cancellation of such Holder’s Note. The Effective Date
shall constitute the Conversion Date under each Note, and each Note shall hereafter be cancelled on the books and records of the
Company and shall represent the right to receive the number of Conversion Shares set forth opposite such Holder’s name on
Schedule I hereto.

3. Issuance
of Warrants. 


 


(a) As of the
Effective Date, (a) in exchange for the applicable outstanding Replacement Warrant, each Holder shall be issued an Amended and
Restated Replacement Warrant in the form of Exhibit A attached hereto, which Amended and Restated Replacement Warrant will
be immediately exercisable as of the Effective Date for the number of shares of Common Stock set forth opposite such Holder’s
name on Schedule I hereto and (b) in exchange for the applicable outstanding Additional Warrant, each Holder shall be issued
an Amended and Restated Additional Warrant in the form of Exhibit B attached hereto, which Amended and Restated Additional
Warrant will be immediately exercisable as of the Effective Date for the number of shares of Common Stock set forth opposite such
Holder’s name on Schedule I hereto. Upon issuance of the Amended and Restated Warrants to each Holder, such Holder’s
Warrants shall be deemed cancelled and extinguished, without need for surrender to the Company of the Warrants or any other further
action by any of the parties to this Agreement, and such Warrants shall thereupon be null and void and have no further force or
effect. Each such Holder agrees that, as of the Effective Date, all rights and obligations of such Holder with respect to the Warrants
or of the Company with respect to the Warrants, as set forth in the Warrants, the Subscription Agreement and any related agreement
of such Holder, including, without limitation, any related document entered into with respect to such Warrants, shall terminate.
Each such Holder agrees to execute such documents and other papers and take such further actions as may be reasonably required
or desired to evidence cancellation of such Holder’s Warrants.


 


(b) As of the
Effective Date, as consideration for early conversion of the Note, the Company will make a conversion payment to the Holder by
issuing the Payment Warrant in the form of Exhibit C attached hereto, which Payment Warrant will be immediately exercisable
as of the Effective Date for the number of shares of Common Stock set forth opposite such Holder’s name on Schedule I
hereto.


 


4. Delivery
of Securities.


 


(a) As soon as
is practicable after the Effective Date, the Company shall (i) instruct the transfer agent to enter in the name of each Holder
a book entry position evidencing the number of Conversion Shares set forth opposite the name of such Holder on Schedule I
hereto, (ii) deliver to each Holder the Amended and Restated Warrants issuable to each Holder and (iii) deliver to each Holder
the Payment Warrant issuable to such Holder.

5. Restrictions
on Transfer. The Conversion Shares, the Amended and Restated Warrants, the Payment Warrants and the shares of Common
Stock issuable upon exercise of the Amended and Restated Warrants and Payment Warrants, have not been registered under the Securities
Act of 1933, as amended (the “Securities Act”), or under any state securities or “blue sky laws,”
and may not be offered, sold, transferred, hypothecated or otherwise assigned except (i) pursuant to a registration statement with
respect to such securities which is effective under the Securities Act or (ii) pursuant to an available exemption from registration
under the Securities Act and in accordance with all applicable state securities and so-called “blue sky laws.” The
Company may require the transferor to provide to the Company an opinion of counsel selected by the transferor and reasonably acceptable
to the Company, the form and substance of which opinion shall be reasonably satisfactory to the Company, to the effect that such
transfer does not require registration of such transferred securities under the Securities Act. Each Holder agrees to be bound
by such restrictions on transfer. Each Holder further consents that the book-entry positions representing the Conversion Shares
may bear a restrictive legend to such effect.


 


6. Representations
and Warranties of the Holder. Each Holder represents and warrants to the Company, as of the date hereof, as follows:


 


(a) Such Holder
is acquiring the shares of Common Stock, the Amended and Restated Warrants and the Payment Warrants (together, the “Securities”)
for such Holder’s own account, as principal, for investment purposes only and not with any intention to resell, distribute
or otherwise dispose of the Securities, as the case may be, in whole or in part.


 


(b) Such Holder
has had an unrestricted opportunity to: (i) obtain information concerning the Securities, the Company and its proposed and existing
business and assets; and (ii) ask questions of, and receive answers from the Company concerning the terms and conditions of the
Securities and to obtain such additional information as may have been necessary to verify the accuracy of the information contained
in the this Agreement or otherwise provided.


 


(c) At the time
such Holder was offered Securities, it was, at the date hereof it is, and on each date on which such Holder exercises the Amended
and Restated Warrants or Payment Warrants, such Holder will be an Accredited Investor, within the meaning of Rule 501 of Regulation D,
and has such knowledge and experience in financial and business matters that he is capable of evaluating the merits and risks of
investing in the Company, and all information that such Holder has provided concerning such Holder, such Holder’s financial
position and knowledge of financial and business matters is true, correct and complete. Such Holder acknowledges and understands
that the Company will rely on the information provided by such Holder in this Agreement and in the Holder Questionnaire annexed
as Exhibit A to such Holder’s Subscription Agreement for purposes of complying with federal and applicable state securities
laws. Such Holder hereby represents that neither such Holder nor any of its Rule 506(d) Related Parties is a “bad actor”
within the meaning of Rule 506(d) promulgated under the Securities Act. For purposes of this Agreement, “Rule 506(d) Related
Party” shall mean a person or entity covered by the “Bad Actor disqualification” provision of Rule 506(d) of
the Securities Act.

(d) Except as
otherwise disclosed in writing by such Holder to the Company, such Holder has not dealt with a broker in connection with the issuance
of the Securities and agrees to indemnify and hold the Company and its officers and directors harmless from any claims for brokerage
or fees in connection with the transactions contemplated herein.


 


(e) Such Holder
is not relying on the Company or any of its management, officers or employees with respect to any legal, investment or tax considerations
involved in the purchase, ownership and disposition of the Securities. Such Holder has relied solely on the advice of, or has consulted
with, in regard to the legal, investment and tax considerations involved in the purchase, ownership and disposition of the Securities,
such Holder’s own legal counsel, business and/or investment adviser, accountant and tax adviser.


 


(f) Such Holder
understands that the Securities, or any securities received upon exercise of the Amended and Restated Warrants or Payment Warrants,
cannot be sold, assigned, transferred, exchanged, hypothecated or pledged, or otherwise disposed of or encumbered except in accordance
with the Securities Act of 1933, as amended (the “Securities Act”) or the Securities and Exchange Act
of 1934, as amended (the “Exchange Act”), and that a market may never exist for the resale of any such
securities. In addition, such Holder understands that the Securities or any securities received upon exercise of the Amended and
Restated Warrants or Payment Warrants, have not been registered under the Securities Act, or under any applicable state securities
or blue sky laws or the laws of any other jurisdiction, and cannot be resold unless they are so registered or unless an exemption
from registration is available. Such Holder understands that there is no current plan to register the Securities or any securities
received upon exercise of the Amended and Restated Warrants or Payment Warrants.

is willing and able to bear the economic and other risks of an investment in the Company for an indefinite period of time. Such
Holder has read and understands the provisions of this Agreement.


 


(h) Such Holder
maintains such Holder’s domicile, and is not merely a transient or temporary resident, at the residence address shown on

(i) If such
Holder is an entity, such Holder is duly organized, validly existing and in good standing under the laws of its jurisdiction of
incorporation or organization, as the case may be. Such Holder has all requisite power and authority to own its properties, to
carry on its business as presently conducted, to enter into and perform the agreements, documents and instruments executed, delivered
and/or contemplated hereby (collectively, the “Transaction Documents”) to which it is a party and to
carry out the transactions contemplated hereby and thereby. The Transaction Documents are valid and binding obligations of such
Holder, enforceable against it in accordance with their terms, except as enforceability may be limited by applicable bankruptcy,
insolvency, moratorium, reorganization or similar laws, from time to time in effect, which affect enforcement of creditors’
rights generally. If applicable, the execution, delivery and performance of the Transaction Documents to which it is a party have
been duly authorized by all necessary action of such Holder. The execution, delivery and performance of the Transaction Documents
and the performance of any transactions contemplated by the Transaction Documents will not: (i) violate, conflict with or result
in a default (whether after the giving of notice, lapse of time or both) under any contract or obligation to which such Holder
is a party or by which it or its assets are bound, or any provision of its organizational documents (if an entity), or cause the
creation of any lien or encumbrance upon any of the assets of such Holder; (ii) violate, conflict with or result in a default (whether
after the giving of notice, lapse of time or both) under, any provision of any law, regulation or rule, or any order of, or any
restriction imposed by any court or other governmental agency applicable to such Holder; (iii) require from such Holder any notice
to, declaration or filing with, or consent or approval of any governmental authority or other third party other than pursuant to
federal or state securities or blue sky laws; or (iv) accelerate any obligation under, or give rise to a right of termination of,
any agreement, permit, license or authorization to which such Holder is a party or by which it is bound.

agents, employees, shareholders, representatives and attorneys, and each of their respective heirs, executors, administrators,

hereby releases and forever discharges the Company and its officers, directors, agents, employees, stockholders, representatives

“Company Claims”), reasonably incurred in investigating, preparing or defending any action, claim, suit,
inquiry, proceeding, investigation or appeal taken from the foregoing by or before any court or governmental, administrative or
other regulatory agency, body or the SEC, whether pending or threatened, whether or not an indemnified party is or may be a party

made by such Holder and contained in this Agreement; or (ii) arise out of or are based upon any breach by such Holder of any representation,

with investigating or defending any such Claim or action; provided, however, that the Company will not be liable in any such case
if and to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged
untrue statement or omission or alleged omission so made in conformity with information furnished by such Holder or any such controlling

Agreement, dated as of [____________], 2018 by and among the Company and the holders thereto (the “Debt Conversion
Agreement”), which provided that certain 8% convertible promissory notes (the “Notes”)
were converted into the right to receive Shares and provided for the cancellation of certain outstanding warrants (the “Prior
Warrants”) in exchange for amended and restated warrants, which Notes and Prior Warrants were issued in the Company’s
private offering solely to accredited investors in accordance with, and subject to, the terms and conditions described in the Subscription
Agreement entered into in August 2017, as amended in November 2017 and March 2018 (the “Subscription Agreement”).
Capitalized terms used herein and not otherwise defined shall have the meanings ascribed to those terms in the Notes or the Debt
Conversion Agreement, as the case may be.


 


This Warrant is subject
to the following terms and conditions:


 


1. Shares.
The Holder has, subject to the terms set forth herein, the right to purchase, at any time during the Warrant Exercise Term, up
to [___________] shares of Common Stock, at a per share exercise price equal to $1.80 (the “Exercise Price”).
The Exercise Price is subject to adjustment as provided in Section 3 hereof.


 






     


     


    

 


2. Exercise
of Warrant. 


 


(a) Exercise.
This Warrant may be exercised by the Holder at any time during the Warrant Exercise Term, in whole or in part, by delivering the
notice of exercise attached as Exhibit A hereto (the “Notice of
Exercise”), duly executed by the Holder to the Company at its principal office, or at such other office as the Company
may designate, accompanied by payment, in cash or by wire transfer of immediately available funds or by check payable to the order
of the Company (the “Purchase Price”). For purposes hereof, “Exercise Date”
shall mean the date on which all deliveries required to be made to the Company upon exercise of this Warrant pursuant to this Section
2(a) shall have been made.


 


(b) Issuance of Shares.
As soon as practicable after the exercise of this Warrant, in whole or in part, in accordance with Section 2(a) hereof,
the Company, at its expense, shall issue to the Holder and instruct the transfer agent to enter in the name of such Holder a book
entry position evidencing the number of validly issued, fully paid and non-assessable Shares to which the Holder shall be entitled
upon such exercise. Partial exercises of this Warrant resulting in purchases of a portion of the total number of Shares available
hereunder shall have the effect of lowering the outstanding number of Shares purchasable hereunder in an amount equal to the applicable
number of Shares purchased. The Holder shall for all purposes hereof be deemed to have become the Holder of record of such Shares
on the date on which the Notice of Exercise and payment of the Purchase Price in accordance with Section 2(a) hereof were
delivered and made, respectively, irrespective of the date the book entry evidencing the issuance was recorded, except that if
the date of such delivery, notice and payment is a date when the stock transfer books of the Company are closed, such person shall
be deemed to have become the holder of record of such Shares at the close of business on the next succeeding date on which the
stock transfer books are open. Shares purchased hereunder shall be reflected on the books and records of the Company by the date
that is three (3) trading days after the latest of (i) the delivery to the Company of the Notice of Exercise and (ii) surrender
of this Warrant (if required).


 


(c) Taxes.  The
issuance of the Shares upon the exercise of this Warrant, and the delivery of certificates or other instruments representing such
Shares, shall be made without charge to the Holder for any tax or other charge of whatever nature in respect of such issuance and
the Company shall bear any such taxes in respect of such issuance.


 


3. Adjustment
of Exercise Price and Number of Shares. 


 


(a) Adjustment for
Reclassification, Consolidation or Merger. If while this Warrant, or any portion hereof, remains outstanding and unexpired
there shall be (i) a reorganization or recapitalization (other than a combination, reclassification, exchange or subdivision of
shares otherwise provided for herein), (ii) a merger or consolidation of the Company with or into another corporation or other
entity in which the Company shall not be the surviving entity, in which the Company shall be the surviving entity but the shares
of the Company’s capital stock outstanding immediately prior to the merger are converted by virtue of the merger into other
property, whether in the form of securities, cash or otherwise, or (iii) a sale or transfer of the Company’s properties and
assets as, or substantially as, an entirety to any other corporation or other entity in one transaction or a series of related
transactions, then, as a part of such reorganization, recapitalization, merger, consolidation, sale or transfer, unless otherwise
directed by the Holder, all necessary or appropriate lawful provisions shall be made so that the Holder shall thereafter be entitled
to receive upon exercise of this Warrant, during the period specified herein and upon payment of the Exercise Price then in effect,
the greatest number of shares of capital stock or other securities or property that a holder of the Shares deliverable upon exercise
of this Warrant would have been entitled to receive in such reorganization, recapitalization, merger, consolidation, sale or transfer
if this Warrant had been exercised immediately prior to such reorganization, recapitalization, merger, consolidation, sale or transfer,
all subject to further adjustment as provided in this Section 3. If the per share consideration payable to the Holder for
Shares in connection with any such transaction is in a form other than cash or marketable securities, then the value of such consideration
shall be determined in good faith by the Company’s Board of Directors. The foregoing provisions of this paragraph shall similarly
apply to successive reorganizations, recapitalizations, mergers, consolidations, sales and transfers and to the capital stock or
securities of any other corporation that are at the time receivable upon the exercise of this Warrant. In all events, appropriate
adjustment shall be made in the application of the provisions of this Warrant with respect to the rights and interests of the Holder
after the transaction, to the end that the provisions of this Warrant shall be applicable after that event, as near as reasonably
may be, in relation to any shares or other property deliverable or issuable after such reorganization, recapitalization, merger,
consolidation, sale or transfer upon exercise of this Warrant.


 






    	 	2	 



     


    

 


(b) Adjustments for
Split, Subdivision or Combination of Shares. If the Company shall at any time subdivide (by any stock split, stock dividend,
recapitalization, reorganization, reclassification or otherwise) the Shares subject to acquisition hereunder, then, after the date
of record for effecting such subdivision, the Exercise Price in effect immediately prior to such subdivision will be proportionately
reduced and the number of Shares subject to acquisition upon exercise of the Warrant will be proportionately increased. If the
Company at any time combines (by reverse stock split, recapitalization, reorganization, reclassification or otherwise) the Shares
subject to acquisition hereunder, then, after the record date for effecting such combination, the Exercise Price in effect immediately
prior to such combination will be proportionately increased and the number of Shares subject to acquisition upon exercise of the
Warrant will be proportionately decreased.


 


(c) Adjustments for
Dividends in Stock or Other Securities or Property. If while this Warrant, or any portion hereof, remains outstanding and unexpired,
the holders of any class of securities as to which purchase rights under this Warrant exist at the time shall have received or,
on or after the record date fixed for the determination of eligible stockholders, shall have become entitled to receive, without
payment therefor, other or additional stock or other securities or property (other than cash) of the Company by way of dividend,
then and in each case, this Warrant shall represent the right to acquire, in addition to the number of shares of such class of
security receivable upon exercise of this Warrant, and without payment of any additional consideration therefor, the amount of
such other or additional stock or other securities or property (other than cash) of the Company that such holder would hold on
the date of such exercise had it been the holder of record of the class of security receivable upon exercise of this Warrant on
the date hereof and had thereafter, during the period from the date hereof to and including the date of such exercise, retained
such shares and/or all other additional stock available to it as aforesaid during said period, giving effect to all adjustments
called for during such period by the provisions of this Section 3.

(d) Reserved.


 


(e) Notice of Adjustments.
Upon any adjustment of the Exercise Price and any increase or decrease in the number of Shares purchasable upon the exercise of
this Warrant, then, and in each such case, the Company, within 30 days thereafter, shall give written notice thereof to the Holder
at the address of such Holder as shown on the books of the Company, which notice shall state the Exercise Price as adjusted and,
if applicable, the increased or decreased number of Shares purchasable upon the exercise of this Warrant, setting forth in reasonable
detail the method of calculation of each.


 


4. Change
in Control.


 


(a) Upon the written
request of the Company, the Holder agrees that, in the event of a Change in Control that is not an asset sale and in which the
sole consideration is cash, either (i) the Holder shall exercise its conversion or purchase right under this Warrant and such exercise
will be deemed effective immediately prior to the consummation of such Change in Control or (ii) if the Holder elects not to exercise
the Warrant, this Warrant will expire upon the consummation of such Change in Control. The Company shall provide the Holder with
written notice of its request relating to the foregoing (together with such reasonable information as such Holder may request in
connection with such contemplated Change in Control giving rise to such notice), which is to be delivered to the Holder not less
than 10 days prior to the closing of the proposed Change in Control.


 


(b) Upon the written
request of the Company, the Holder agrees that, in the event of a Change in Control that is an “arms-length” sale of
all or substantially all of the Company’s assets (and only its assets) to a third party that is not an Affiliate (as defined
below) of the Company (a “True Asset Sale”), either (i) the Holder shall exercise its conversion or purchase
right under this Warrant and such exercise will be deemed effective immediately prior to the consummation of such Change in Control
or (ii) if the Holder elects not to exercise the Warrant, this Warrant will continue until the expiration of the Warrant Expiration
Term if the Company continues as a going concern following the closing of any such True Asset Sale. The Company shall provide the
Holder with written notice of its request relating to the foregoing (together with such reasonable information as such Holder may
request in connection with such contemplated Change in Control giving rise to such notice), which is to be delivered to the Holder
not less than 10 days prior to the closing of the proposed Change in Control. As used herein “Affiliate”
shall mean any person or entity that owns or controls directly or indirectly 10% or more of the stock of the Company, and any person
or entity that controls or is controlled by or is under common control with such persons or entities.


 


(c) Upon the written
request of the Company, the Holder agrees that, in the event of a stock for stock Change in Control of the Company by a publicly
traded acquirer if, on the record date for the Change in Control, the fair market value of the Shares (or other securities issuable
upon exercise of this Warrant) is equal to or greater than two times the Exercise Price, the Company may require the Warrant to
be deemed automatically exercised and the Holder shall participate in the Change in Control as a holder of the Shares (or other
securities issuable upon exercise of the Warrant) on the same terms as other holders of the same class of securities of the Company.


 






    	 	4	 



     


    

 


(d) Upon the closing
of any Change in Control other than those particularly described in subsections (a), (b) and (c) above of this Section 4,
the successor entity, if any, and if applicable, shall assume the obligations of this Warrant, and this Warrant shall be exercisable
for the same securities, cash, and property as would be payable for the Shares issuable upon exercise of the unexercised portion
of this Warrant as if such Shares were outstanding on the record date for the Change in Control and subsequent closing. The Exercise
Price and/or number of Shares shall be adjusted accordingly.


 


5. Notices.
All notices, requests, consents and other communications required or permitted under this Warrant shall be in writing and shall
be deemed delivered (a) three business days after being sent by registered or certified mail, return receipt requested, postage
prepaid or (b) one business day after being sent via a reputable nationwide overnight courier service guaranteeing next business
day delivery or (c) on the business day of delivery if sent by email transmission, in each case to the intended recipient as set

NEUROONE MEDICAL TECHNOLOGIES CORPORATION


 


COMMON STOCK PURCHASE WARRANT


 


_________________


 


This
Certified That, for value received, [_______________] (the “Holder”) is entitled to subscribe
for and purchase from NeuroOne Medical Technologies Corporation, a Delaware
corporation (the “Company”), at any time commencing on the date hereof and expiring on November 21, 2021
(the “Warrant Exercise Term”), the Shares at the Exercise Price (each as defined in Section 1
below).


 


This Amended and Restated
Common Stock Purchase Warrant (the “Warrant”) is issued in connection with the Series 2 Notes Debt Conversion
Agreement, dated as of [____________], by and among the Company and the holders thereto (the “Debt Conversion Agreement”),
which provided that certain 8% convertible promissory notes (the “Notes”) were converted into the right
to receive Shares and provided for the cancellation of certain outstanding warrants (the “Prior Warrants”)
in exchange for amended and restated warrants, which Notes and Prior Warrants were issued in the Company’s private offering
solely to accredited investors in accordance with, and subject to, the terms and conditions described in the Subscription Agreement
entered into in August 2017, as amended in November 2017 and March 2018 (the “Subscription Agreement”).
Capitalized terms used herein and not otherwise defined shall have the meanings ascribed to those terms in the Notes or the Debt
Conversion Agreement, as the case may be.


 


This Warrant is subject
to the following terms and conditions:


 


1. Shares.
The Holder has, subject to the terms set forth herein, the right to purchase, at any time during the Warrant Exercise Term, up
to [___________] shares of Common Stock, at a per share exercise price equal to $1.80 (the “Exercise Price”).
The Exercise Price is subject to adjustment as provided in Section 3 hereof.


 






     


     


    

 


2. Exercise
of Warrant. 


 


(a) Exercise.
This Warrant may be exercised by the Holder at any time during the Warrant Exercise Term, in whole or in part, by delivering the
notice of exercise attached as Exhibit A hereto (the “Notice of
Exercise”), duly executed by the Holder to the Company at its principal office, or at such other office as the Company
may designate, accompanied by payment, in cash or by wire transfer of immediately available funds or by check payable to the order
of the Company (the “Purchase Price”). For purposes hereof, “Exercise Date”
shall mean the date on which all deliveries required to be made to the Company upon exercise of this Warrant pursuant to this Section
2(a) shall have been made.


 


(b) Issuance of Shares.
As soon as practicable after the exercise of this Warrant, in whole or in part, in accordance with Section 2(a) hereof,
the Company, at its expense, shall issue to the Holder and instruct the transfer agent to enter in the name of such Holder a book
entry position evidencing the number of validly issued, fully paid and non-assessable Shares to which the Holder shall be entitled
upon such exercise. Partial exercises of this Warrant resulting in purchases of a portion of the total number of Shares available
hereunder shall have the effect of lowering the outstanding number of Shares purchasable hereunder in an amount equal to the applicable
number of Shares purchased. The Holder shall for all purposes hereof be deemed to have become the Holder of record of such Shares
on the date on which the Notice of Exercise and payment of the Purchase Price in accordance with Section 2(a) hereof were
delivered and made, respectively, irrespective of the date the book entry evidencing the issuance was recorded, except that if
the date of such delivery, notice and payment is a date when the stock transfer books of the Company are closed, such person shall
be deemed to have become the holder of record of such Shares at the close of business on the next succeeding date on which the
stock transfer books are open. Shares purchased hereunder shall be reflected on the books and records of the Company by the date
that is three (3) trading days after the latest of (i) the delivery to the Company of the Notice of Exercise and (ii) surrender
of this Warrant (if required).


 


(c) Taxes.  The
issuance of the Shares upon the exercise of this Warrant, and the delivery of certificates or other instruments representing such
Shares, shall be made without charge to the Holder for any tax or other charge of whatever nature in respect of such issuance and
the Company shall bear any such taxes in respect of such issuance.


 


3. Adjustment
of Exercise Price and Number of Shares. 


 


(a) Adjustment for
Reclassification, Consolidation or Merger. If while this Warrant, or any portion hereof, remains outstanding and unexpired
there shall be (i) a reorganization or recapitalization (other than a combination, reclassification, exchange or subdivision of
shares otherwise provided for herein), (ii) a merger or consolidation of the Company with or into another corporation or other
entity in which the Company shall not be the surviving entity, in which the Company shall be the surviving entity but the shares
of the Company’s capital stock outstanding immediately prior to the merger are converted by virtue of the merger into other
property, whether in the form of securities, cash or otherwise, or (iii) a sale or transfer of the Company’s properties and
assets as, or substantially as, an entirety to any other corporation or other entity in one transaction or a series of related
transactions, then, as a part of such reorganization, recapitalization, merger, consolidation, sale or transfer, unless otherwise
directed by the Holder, all necessary or appropriate lawful provisions shall be made so that the Holder shall thereafter be entitled
to receive upon exercise of this Warrant, during the period specified herein and upon payment of the Exercise Price then in effect,
the greatest number of shares of capital stock or other securities or property that a holder of the Shares deliverable upon exercise
of this Warrant would have been entitled to receive in such reorganization, recapitalization, merger, consolidation, sale or transfer
if this Warrant had been exercised immediately prior to such reorganization, recapitalization, merger, consolidation, sale or transfer,
all subject to further adjustment as provided in this Section 3. If the per share consideration payable to the Holder for
Shares in connection with any such transaction is in a form other than cash or marketable securities, then the value of such consideration
shall be determined in good faith by the Company’s Board of Directors. The foregoing provisions of this paragraph shall similarly
apply to successive reorganizations, recapitalizations, mergers, consolidations, sales and transfers and to the capital stock or
securities of any other corporation that are at the time receivable upon the exercise of this Warrant. In all events, appropriate
adjustment shall be made in the application of the provisions of this Warrant with respect to the rights and interests of the Holder
after the transaction, to the end that the provisions of this Warrant shall be applicable after that event, as near as reasonably
may be, in relation to any shares or other property deliverable or issuable after such reorganization, recapitalization, merger,
consolidation, sale or transfer upon exercise of this Warrant.


 






    	 	2	 



     


    

 


(b) Adjustments for
Split, Subdivision or Combination of Shares. If the Company shall at any time subdivide (by any stock split, stock dividend,
recapitalization, reorganization, reclassification or otherwise) the Shares subject to acquisition hereunder, then, after the date
of record for effecting such subdivision, the Exercise Price in effect immediately prior to such subdivision will be proportionately
reduced and the number of Shares subject to acquisition upon exercise of the Warrant will be proportionately increased. If the
Company at any time combines (by reverse stock split, recapitalization, reorganization, reclassification or otherwise) the Shares
subject to acquisition hereunder, then, after the record date for effecting such combination, the Exercise Price in effect immediately
prior to such combination will be proportionately increased and the number of Shares subject to acquisition upon exercise of the
Warrant will be proportionately decreased.


 


(c) Adjustments for
Dividends in Stock or Other Securities or Property. If while this Warrant, or any portion hereof, remains outstanding and unexpired,
the holders of any class of securities as to which purchase rights under this Warrant exist at the time shall have received or,
on or after the record date fixed for the determination of eligible stockholders, shall have become entitled to receive, without
payment therefor, other or additional stock or other securities or property (other than cash) of the Company by way of dividend,
then and in each case, this Warrant shall represent the right to acquire, in addition to the number of shares of such class of
security receivable upon exercise of this Warrant, and without payment of any additional consideration therefor, the amount of
such other or additional stock or other securities or property (other than cash) of the Company that such holder would hold on
the date of such exercise had it been the holder of record of the class of security receivable upon exercise of this Warrant on
the date hereof and had thereafter, during the period from the date hereof to and including the date of such exercise, retained
such shares and/or all other additional stock available to it as aforesaid during said period, giving effect to all adjustments
called for during such period by the provisions of this Section 3.

(d) Reserved.


 


(e) Notice of Adjustments.
Upon any adjustment of the Exercise Price and any increase or decrease in the number of Shares purchasable upon the exercise of
this Warrant, then, and in each such case, the Company, within 30 days thereafter, shall give written notice thereof to the Holder
at the address of such Holder as shown on the books of the Company, which notice shall state the Exercise Price as adjusted and,
if applicable, the increased or decreased number of Shares purchasable upon the exercise of this Warrant, setting forth in reasonable
detail the method of calculation of each.


 


4. Change
in Control.


 


(a) Upon the written
request of the Company, the Holder agrees that, in the event of a Change in Control that is not an asset sale and in which the
sole consideration is cash, either (i) the Holder shall exercise its conversion or purchase right under this Warrant and such exercise
will be deemed effective immediately prior to the consummation of such Change in Control or (ii) if the Holder elects not to exercise
the Warrant, this Warrant will expire upon the consummation of such Change in Control. The Company shall provide the Holder with
written notice of its request relating to the foregoing (together with such reasonable information as such Holder may request in
connection with such contemplated Change in Control giving rise to such notice), which is to be delivered to the Holder not less
than 10 days prior to the closing of the proposed Change in Control.


 


(b) Upon the written
request of the Company, the Holder agrees that, in the event of a Change in Control that is an “arms-length” sale of
all or substantially all of the Company’s assets (and only its assets) to a third party that is not an Affiliate (as defined
below) of the Company (a “True Asset Sale”), either (i) the Holder shall exercise its conversion or purchase
right under this Warrant and such exercise will be deemed effective immediately prior to the consummation of such Change in Control
or (ii) if the Holder elects not to exercise the Warrant, this Warrant will continue until the expiration of the Warrant Expiration
Term if the Company continues as a going concern following the closing of any such True Asset Sale. The Company shall provide the
Holder with written notice of its request relating to the foregoing (together with such reasonable information as such Holder may
request in connection with such contemplated Change in Control giving rise to such notice), which is to be delivered to the Holder
not less than 10 days prior to the closing of the proposed Change in Control. As used herein “Affiliate”
shall mean any person or entity that owns or controls directly or indirectly 10% or more of the stock of the Company, and any person
or entity that controls or is controlled by or is under common control with such persons or entities.


 


(c) Upon the written
request of the Company, the Holder agrees that, in the event of a stock for stock Change in Control of the Company by a publicly
traded acquirer if, on the record date for the Change in Control, the fair market value of the Shares (or other securities issuable
upon exercise of this Warrant) is equal to or greater than two times the Exercise Price, the Company may require the Warrant to
be deemed automatically exercised and the Holder shall participate in the Change in Control as a holder of the Shares (or other
securities issuable upon exercise of the Warrant) on the same terms as other holders of the same class of securities of the Company.

(d) Upon the closing
of any Change in Control other than those particularly described in subsections (a), (b) and (c) above of this Section 4,
the successor entity, if any, and if applicable, shall assume the obligations of this Warrant, and this Warrant shall be exercisable
for the same securities, cash, and property as would be payable for the Shares issuable upon exercise of the unexercised portion
of this Warrant as if such Shares were outstanding on the record date for the Change in Control and subsequent closing. The Exercise
Price and/or number of Shares shall be adjusted accordingly.


 


5. Notices.
All notices, requests, consents and other communications required or permitted under this Warrant shall be in writing and

NEUROONE MEDICAL TECHNOLOGIES CORPORATION


 


COMMON STOCK PURCHASE WARRANT


 


_________________


 


This
Certified That, for value received, [_______________] (the “Holder”) is entitled to subscribe
for and purchase from NeuroOne Medical Technologies Corporation, a Delaware
corporation (the “Company”), at any time commencing on the date hereof and expiring on November 21, 2021
(the “Warrant Exercise Term”), the Shares at the Exercise Price (each as defined in Section 1
below).


 


This Common Stock Purchase
Warrant (the “Warrant”) is issued in connection with the Series 2 Notes Debt Conversion Agreement, dated
as of [____________], by and among the Company and the holders thereto (the “Debt Conversion Agreement”),
which provided that certain 8% convertible promissory notes (the “Notes”) were converted into the right
to receive Shares, provided for the cancellation of certain outstanding warrants in exchange for amended and restated warrants
(the “A&R Warrants”), and provided for the issuance of new warrants, including this Warrant, as payment
for and in consideration for the early conversion of the Notes. Capitalized terms used herein and not otherwise defined shall have
the meanings ascribed to those terms in the Notes or the Debt Conversion Agreement, as the case may be.


 


This Warrant is subject
to the following terms and conditions:


 


1. Shares.
The Holder has, subject to the terms set forth herein, the right to purchase, at any time during the Warrant Exercise Term, up
to [___________] shares of Common Stock, at a per share exercise price equal to $1.80 (the “Exercise Price”).
The Exercise Price is subject to adjustment as provided in Section 3 hereof.


 






     


     


    

 


2. Exercise
of Warrant. 


 


(a) Exercise.
This Warrant may be exercised by the Holder at any time during the Warrant Exercise Term, in whole or in part, by delivering the
notice of exercise attached as Exhibit A hereto (the “Notice of
Exercise”), duly executed by the Holder to the Company at its principal office, or at such other office as the Company
may designate, accompanied by payment, in cash or by wire transfer of immediately available funds or by check payable to the order
of the Company (the “Purchase Price”). For purposes hereof, “Exercise Date”
shall mean the date on which all deliveries required to be made to the Company upon exercise of this Warrant pursuant to this Section
2(a) shall have been made.


 


(b) Issuance of Shares.
As soon as practicable after the exercise of this Warrant, in whole or in part, in accordance with Section 2(a) hereof,
the Company, at its expense, shall issue to the Holder and instruct the transfer agent to enter in the name of such Holder a book
entry position evidencing the number of validly issued, fully paid and non-assessable Shares to which the Holder shall be entitled
upon such exercise. Partial exercises of this Warrant resulting in purchases of a portion of the total number of Shares available
hereunder shall have the effect of lowering the outstanding number of Shares purchasable hereunder in an amount equal to the applicable
number of Shares purchased. The Holder shall for all purposes hereof be deemed to have become the Holder of record of such Shares
on the date on which the Notice of Exercise and payment of the Purchase Price in accordance with Section 2(a) hereof were
delivered and made, respectively, irrespective of the date the book entry evidencing the issuance was recorded, except that if
the date of such delivery, notice and payment is a date when the stock transfer books of the Company are closed, such person shall
be deemed to have become the holder of record of such Shares at the close of business on the next succeeding date on which the
stock transfer books are open. Shares purchased hereunder shall be reflected on the books and records of the Company by the date
that is three (3) trading days after the latest of (i) the delivery to the Company of the Notice of Exercise and (ii) surrender
of this Warrant (if required).


 


(c) Taxes.  The
issuance of the Shares upon the exercise of this Warrant, and the delivery of certificates or other instruments representing such
Shares, shall be made without charge to the Holder for any tax or other charge of whatever nature in respect of such issuance and
the Company shall bear any such taxes in respect of such issuance.


 


3. Adjustment
of Exercise Price and Number of Shares. 


 


(a) Adjustment for
Reclassification, Consolidation or Merger. If while this Warrant, or any portion hereof, remains outstanding and unexpired
there shall be (i) a reorganization or recapitalization (other than a combination, reclassification, exchange or subdivision of
shares otherwise provided for herein), (ii) a merger or consolidation of the Company with or into another corporation or other
entity in which the Company shall not be the surviving entity, in which the Company shall be the surviving entity but the shares
of the Company’s capital stock outstanding immediately prior to the merger are converted by virtue of the merger into other
property, whether in the form of securities, cash or otherwise, or (iii) a sale or transfer of the Company’s properties and
assets as, or substantially as, an entirety to any other corporation or other entity in one transaction or a series of related
transactions, then, as a part of such reorganization, recapitalization, merger, consolidation, sale or transfer, unless otherwise
directed by the Holder, all necessary or appropriate lawful provisions shall be made so that the Holder shall thereafter be entitled
to receive upon exercise of this Warrant, during the period specified herein and upon payment of the Exercise Price then in effect,
the greatest number of shares of capital stock or other securities or property that a holder of the Shares deliverable upon exercise
of this Warrant would have been entitled to receive in such reorganization, recapitalization, merger, consolidation, sale or transfer
if this Warrant had been exercised immediately prior to such reorganization, recapitalization, merger, consolidation, sale or transfer,
all subject to further adjustment as provided in this Section 3. If the per share consideration payable to the Holder for
Shares in connection with any such transaction is in a form other than cash or marketable securities, then the value of such consideration
shall be determined in good faith by the Company’s Board of Directors. The foregoing provisions of this paragraph shall similarly
apply to successive reorganizations, recapitalizations, mergers, consolidations, sales and transfers and to the capital stock or
securities of any other corporation that are at the time receivable upon the exercise of this Warrant. In all events, appropriate
adjustment shall be made in the application of the provisions of this Warrant with respect to the rights and interests of the Holder
after the transaction, to the end that the provisions of this Warrant shall be applicable after that event, as near as reasonably
may be, in relation to any shares or other property deliverable or issuable after such reorganization, recapitalization, merger,
consolidation, sale or transfer upon exercise of this Warrant.


 






    	 	2	 



     


    

 


(b) Adjustments for
Split, Subdivision or Combination of Shares. If the Company shall at any time subdivide (by any stock split, stock dividend,
recapitalization, reorganization, reclassification or otherwise) the Shares subject to acquisition hereunder, then, after the date
of record for effecting such subdivision, the Exercise Price in effect immediately prior to such subdivision will be proportionately
reduced and the number of Shares subject to acquisition upon exercise of the Warrant will be proportionately increased. If the
Company at any time combines (by reverse stock split, recapitalization, reorganization, reclassification or otherwise) the Shares
subject to acquisition hereunder, then, after the record date for effecting such combination, the Exercise Price in effect immediately
prior to such combination will be proportionately increased and the number of Shares subject to acquisition upon exercise of the
Warrant will be proportionately decreased.


 


(c) Adjustments for
Dividends in Stock or Other Securities or Property. If while this Warrant, or any portion hereof, remains outstanding and unexpired,
the holders of any class of securities as to which purchase rights under this Warrant exist at the time shall have received or,
on or after the record date fixed for the determination of eligible stockholders, shall have become entitled to receive, without
payment therefor, other or additional stock or other securities or property (other than cash) of the Company by way of dividend,
then and in each case, this Warrant shall represent the right to acquire, in addition to the number of shares of such class of
security receivable upon exercise of this Warrant, and without payment of any additional consideration therefor, the amount of
such other or additional stock or other securities or property (other than cash) of the Company that such holder would hold on
the date of such exercise had it been the holder of record of the class of security receivable upon exercise of this Warrant on
the date hereof and had thereafter, during the period from the date hereof to and including the date of such exercise, retained
such shares and/or all other additional stock available to it as aforesaid during said period, giving effect to all adjustments
called for during such period by the provisions of this Section 3.


 






    	 	3	 



     


    

 


(d) Reserved.


 


(e) Notice of Adjustments.
Upon any adjustment of the Exercise Price and any increase or decrease in the number of Shares purchasable upon the exercise of
this Warrant, then, and in each such case, the Company, within 30 days thereafter, shall give written notice thereof to the Holder
at the address of such Holder as shown on the books of the Company, which notice shall state the Exercise Price as adjusted and,
if applicable, the increased or decreased number of Shares purchasable upon the exercise of this Warrant, setting forth in reasonable
detail the method of calculation of each.


 


4. Change
in Control.


 


(a) Upon the written
request of the Company, the Holder agrees that, in the event of a Change in Control that is not an asset sale and in which the
sole consideration is cash, either (i) the Holder shall exercise its conversion or purchase right under this Warrant and such exercise
will be deemed effective immediately prior to the consummation of such Change in Control or (ii) if the Holder elects not to exercise
the Warrant, this Warrant will expire upon the consummation of such Change in Control. The Company shall provide the Holder with
written notice of its request relating to the foregoing (together with such reasonable information as such Holder may request in
connection with such contemplated Change in Control giving rise to such notice), which is to be delivered to the Holder not less
than 10 days prior to the closing of the proposed Change in Control.


 


(b) Upon the written
request of the Company, the Holder agrees that, in the event of a Change in Control that is an “arms-length” sale of
all or substantially all of the Company’s assets (and only its assets) to a third party that is not an Affiliate (as defined
below) of the Company (a “True Asset Sale”), either (i) the Holder shall exercise its conversion or purchase
right under this Warrant and such exercise will be deemed effective immediately prior to the consummation of such Change in Control
or (ii) if the Holder elects not to exercise the Warrant, this Warrant will continue until the expiration of the Warrant Expiration
Term if the Company continues as a going concern following the closing of any such True Asset Sale. The Company shall provide the
Holder with written notice of its request relating to the foregoing (together with such reasonable information as such Holder may
request in connection with such contemplated Change in Control giving rise to such notice), which is to be delivered to the Holder
not less than 10 days prior to the closing of the proposed Change in Control. As used herein “Affiliate”
shall mean any person or entity that owns or controls directly or indirectly 10% or more of the stock of the Company, and any person
or entity that controls or is controlled by or is under common control with such persons or entities.


 


(c) Upon the written
request of the Company, the Holder agrees that, in the event of a stock for stock Change in Control of the Company by a publicly
traded acquirer if, on the record date for the Change in Control, the fair market value of the Shares (or other securities issuable
upon exercise of this Warrant) is equal to or greater than two times the Exercise Price, the Company may require the Warrant to
be deemed automatically exercised and the Holder shall participate in the Change in Control as a holder of the Shares (or other
securities issuable upon exercise of the Warrant) on the same terms as other holders of the same class of securities of the Company.


 






    	 	4	 



     


    

 


(d) Upon the closing
of any Change in Control other than those particularly described in subsections (a), (b) and (c) above of this Section 4,
the successor entity, if any, and if applicable, shall assume the obligations of this Warrant, and this Warrant shall be exercisable
for the same securities, cash, and property as would be payable for the Shares issuable upon exercise of the unexercised portion
of this Warrant as if such Shares were outstanding on the record date for the Change in Control and subsequent closing. The Exercise
Price and/or number of Shares shall be adjusted accordingly.


 


5. Notices.
All notices, requests, consents and other communications required or permitted under this Warrant shall be in writing and shall
be deemed delivered (a) three business days after being sent by registered or certified mail, return receipt requested, postage
prepaid or (b) one business day after being sent via a reputable nationwide overnight courier service guaranteeing next business
day delivery or (c) on the business day of delivery if sent by email transmission, in each case to the intended recipient as set

such Shares; (b) the undersigned is aware of the Company’s business affairs and financial condition and has acquired sufficient
information about the Company to reach an informed and knowledgeable decision regarding its investment in the Company; (c) the
undersigned is experienced in making investments of this type and has such knowledge and background in financial and business matters
that the undersigned is capable of evaluating the merits and risks of this investment and protecting the undersigned’s own
interests; (d) the undersigned understands that the Shares issuable upon exercise of this Warrant have not been registered under
the Securities Act of 1933, as amended (the “Securities Act”), by reason of a specific exemption from
the registration provisions of the Securities Act, which exemption depends upon, among other things, the bona fide nature of the
investment intent as expressed herein, and, because such securities have not been registered under the Securities Act, they must
be held indefinitely unless subsequently registered under the Securities Act or an exemption from such registration is available;
(e) the undersigned is aware that the Shares may not be sold pursuant to Rule 144 adopted under the Securities Act unless certain
conditions are met and until the undersigned has held the Shares for the period prescribed by Rule 144, that among the conditions
for use of Rule 144 is the availability of current information to the public about the Company and that the Company has not made
such information available and has no present plans to do so; and (f) the undersigned agrees not to make any disposition of all
or any part of the Shares unless and until there is then in effect a registration statement under the Securities Act covering such
proposed disposition and such disposition is made in accordance with said registration statement, or the undersigned has provided
the Company with an opinion of counsel satisfactory to the Company, stating that such registration is not required.
